Once a firm booking has been made an invoice will be generated. If the course is cancelled over 28 days prior to the course a full refund will be given. If it within 14 days a 50 % refund will be given. Less than 14 days no refund. Invoices should be paid in full within 30 days of the invoice. Otherwise they can be subjected to an 8% increase in the invoice, in line with the late payment of commercial debts.
